Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Friday - May 2, 2014 - 9:35am
bottom line

We are no longer issuing danger ratings, but dangerous wet avalanche conditions exist in the backcountry and will continue through the weekend. Natural loose wet avalanches entraining saturated fresh snow are likely in steep terrain, especially during the heat of the day. Avoid and stay out from under steep slopes with wet surface snow. With very warm temperatures expected this weekend, careful snowpack evaluation, cautious route-finding, and conservative decision making will be essential for safe travel in the backcountry.

current conditions

There's still very good snow coverage in the mountains around Logan, with filled-in avalanche paths from widespread natural avalanches in February and lingering mid-elevation snow allowing good access to quality spring riding. We're done for the season, but avalanches continue, and very warm temperatures will create dangerous wet avalanche conditions this weekend in steep upper elevation terrain. It's 41 degrees this morning up at the 8400' Tony Grove Lake Snotel, and there's 80 inches of total snow containing around 125% of average water for the date. It's 39 degrees at the 9700' CSI Logan Peak weather station, with southwest winds averaging around 20 mph.

recent activity

We received reports of numerous unintentionally triggered avalanches in the Central Wasatch in the last days of April, and a few people got caught and carried by soft wind slab avalanches involving fresh storm snow. Thankfully, no injuries were reported.

In the Logan Zone- Observers reported a couple avalanches involving new snow instabilities during last weekend's stormy weather; a good sized natural cornice-fall triggered avalanche in a popular area in Providence Canyon on Saturday, and a long-running intentionally snow skater triggered soft slab on the north side of Mendon Peak in the Wellsville Mountain Wilderness on Sunday. Also, I could see evidence of fairly widespread recent natural loose wet activity in the Central Wellsville Range yesterday afternoon.

Avalanche Problem 1
type aspect/elevation characteristics
over the next 10 hours

As the fresh snow warms, it's becoming slushy and saturated, and loose wet avalanches entraining the fresh snow are likely in steep terrain, especially during the midday heat. Natural wet avalanches are likely this weekend, so you should stay off and out from under steep slopes with saturated surface snow. Especially avoid steep-sided gullies and steep slopes above trees, be aware of other potential terrain traps.
